I am seeking a way to eliminate double quotation marks from a string without using the replace function

I need assistance in removing double quotes from the string "Hello".

I have an array var ary = ['a', 'b' , 'c'] When I extract a value from the array, it returns the value in string format, such as ary[0] = "a", but I want it to be just a.

I am working with a JSON file that looks like this:

{
   "a":{
       "name" : "Emma"
     },
   "b":{
       "name" : "Harry"
     },
   "c":{
       "name" : "Jonny"
     }
 }

I want to retrieve values from this JSON using the array, like ary[0].name = Emma

NOTE: I have tried using

str.replace(/\"/gi,"");   &&  str.replace(/"/gi,"");

. If you have any other ideas on how to achieve this, please let me know as soon as possible.

Answer №1

If I have correctly understood your needs, you can simply utilize bracket notation in JavaScript like this: [obj['a'].name]

let obj = {
    a: {
        "name": "Sophia"
    },
    b: {
        "name": "Oliver"
    },
    c: {
        "name": "Liam"
    }
};

let keys = ['a', 'b', 'c'];

for (let i = 0; i < keys.length; i++) {
    console.log(obj[keys[i]].name);
}

By passing the property key as a string to the bracket notation, you will get the corresponding value returned.
